Abstract
The invention discloses a kind of sewage disposal precipitating reagent, it is characterised in that and the precipitating reagent includes polyacrylamide, with the sodium hydroxyethyl cellulose aqueous solution, potassium silicate aqueous solution, wherein, the mass ratio of sodium hydroxyethlcellulose and potassium silicate is 1：10—1：20, the mass ratio of the polyacrylamide and sodium hydroxyethyl cellulose is 1:2‑1:5.Precipitation agent prescription of the present invention is simple, and raw material sources are extensive, price is low, strong operability, can industrial applications.
Description
Technical field
The invention belongs to field of environmental treatment equipment, and in particular to a kind of sewage disposal precipitating reagent.
Background technology
In general, it is inorganic in the flco size of formation, compactness, sinking speed and final flocculating effect etc.
Low molecule and high polymer coagulant are not so good as inorganic organic polymer molecule composite flocculation agent, while the former is also obvious more for dosage
In the latter.Anionic organic polymer flocculant can not provide for negatively charged colloidal particle neutralizes charge effect, individually makees
For flocculant when poor effect.Inorganic flocculating agent is practical to the water process of various complicated ingredients, can effectively remove micro-nano
The fine-grained particles thing of level, but the floccule body generated is small, and dosage is big.And organic flocculant dosage is few, flocculation rate is fast, is coexisted
Salt, medium pH and temperature influence are smaller, and the sludge quantity of generation is small.- COOH- ,-the NH- ,-SO3- of organic polymer institute band ,-
The hydrophilic radicals such as OH- can have chain, cyclic structure, and pollutant can be made to enter flco, good decoloring performance.But some organic high scores
Sub- material or its hydrolysis, catabolite it is toxic, or synthesis price it is higher, so now it is more be by inorganic flocculating agent with it is organic
Flocculant is used in combination, or the high-valence cationics such as Fe3+, AI3+ are introduced organic flocculant, effectively overcomes inorganic flocculating agent point
The short deficiency of subchain, big floccule body is formed by the bridge formation between particulate, swept off by volume except molecule.
The content of the invention
Present invention aims at a kind of sewage disposal precipitating reagent and preparation method thereof is provided, the precipitating reagent includes poly- third

Than 1：10—1：20, the mass ratio of the polyacrylamide and sodium hydroxyethyl cellulose is 1:2-1:5.
Another object of the present invention is to provide the preparation method of above-mentioned precipitating reagent：By polyacrylamide and carboxyethylcellulose
After plain sodium water solution mixing, agitating and heating 2h under the conditions of being 20~35 DEG C in temperature with water bath with thermostatic control bed, potassium silicate is then added
The aqueous solution, stirring at normal temperature 0.5h, precipitating reagent is made.
Described potassium silicate aqueous solution and the dissolving ratio of water are 1:50~1:100.
Described sodium hydroxyethlcellulose and the dissolving ratio of water are 1:80~1:100.
The beneficial effects of the present invention are：
(1) formula is simple, and raw material sources are extensive, price is low, strong operability, can industrial applications.
(2) this precipitating reagent uses sodium hydroxyethlcellulose precipitating reagent on the basis of traditional flocculant polyacrylamide, together
When introduce potassium silicate cosolvent, the advantages of mixed precipitant can play every kind of composition, improve deposition efficiency, deposition efficiency is reachable
More than 99%.
